Google Translate and duoBooks both turn one language into another, but they are built for different jobs. Google Translate is a fast, free translator for text you paste, type, or point your camera at. duoBooks is a reading app: you read whole books in the language you are learning, and you tap any word or sentence to translate it right on the page. Here is how they compare, and when to use each.

Google Translate is one of the best free tools for quick translation. Paste a paragraph, type a question, or point your camera at a sign, and you get an answer in seconds across a huge number of languages. If you need to understand a single message, a menu, or a web page right now, it is hard to beat. duoBooks does not try to replace that. It is built for a different moment: when you want to sit down and read a whole book in another language.
A plain translator only sees the text you give it. When you read a book, that means copying a word or line out, switching apps, and losing your place. duoBooks works inside the book. Tap a word and it also reads the sentence around it, so you get the meaning that fits right there — including idioms and phrasal verbs, which fall apart when you translate them word by word. Tap a whole sentence and it keeps the tone and works out who the pronouns mean. The words you save become spaced-repetition flashcards, you can hear anything read aloud in 47 languages, and on Android e-ink readers duoBooks switches to a reading mode made for those screens. In short: Google Translate hands you a translation; duoBooks helps you read and remember.
Use Google Translate when you need a quick, one-off translation of something. Use duoBooks when you want to read a book in another language and actually learn it as you go. They are complementary, and many people use both. If your goal is to read more and grow your vocabulary, try reading your next book in duoBooks. Learn English by reading, or see what duoBooks is.
